fī Asmāʾ al-Ṣaḥābah (The Lions of the Thicket on the Names of the Companions), and of al-Kāmil fī al-Tārīkh (The Complete History), which is among the very best of the annalistic works. He began it with the creation itself and carried it through to the year 628 AH. He used to travel frequently to Baghdad, and [he] enjoyed special favor with the rulers of Mosul, even serving as vizier to some of them, as has already been noted. In his final years he settled in Baghdad, honored and revered, until he died there in Shaʿbān of this same year at the age of seventy-five—may Allah have mercy on him.
As for his brother, [Majd al-Dīn] Abū al-Saʿādāt al-Mubārak (1), he is the author of Jāmiʿ al-Uṣūl and other works.
Their brother, the vizier Ḍiyāʾ al-Dīn Abū al-Fatḥ Naṣr Allah (2), was (3) vizier to al-Malik al-Afḍal (4) ʿAlī ibn al-Nāṣir, the conqueror of Jerusalem and lord of Damascus, as mentioned earlier.
Regarding Jazīrat Ibn ʿUmar, some say it was named after a man called ʿAbd al-ʿAzīz (5) ibn ʿUmar from the village of Barqaʿīd (6); others maintain it is attributed to the two sons of ʿUmar—Aws and Kāmil, the sons of ʿUmar ibn Aws al-Taghlibī. Allah knows best. This point was clarified by Qāḍī Ibn Khallikān (7), may Allah Most High show him mercy.
Ibn al-Mustawfī al-Arbalī (8)—Mubārak ibn Aḥmad ibn Mubārak ibn Mahūb ibn Ghunaymah ibn Ghālib, the eminent scholar Sharf al-Dīn Abū al-Barakāt al-Lakhmī al-Arbalī—was an authority in numerous disciplines such as hadith, biographical evaluation, literature, and arithmetic (9). He produced many works and possessed abundant virtues. Qāḍī Shams al-Dīn Ibn Khallikān treated his biography at length in al-Wafayāt (10), doing so with excellence and benefit. May Allah have mercy on them all.
